I agree, having tried to change all my double numbers to single precision
while at the same time going from a 16 bit machine to a 32 bit machine, it
was a disaster, because of trying to change Forth systems from F83s to
Wn32Forth at the same time. It is working much better to stick with the
double numbers until the conversion is complete to the new 32 bit Forth.

Any constructive hints about my new web page will be appreciated.

The home page takes uncomfortably long to load with my 56K modem. Text
or a lower-resolution graphic would improve that.

The blue underlining in the graphic gives the false impression of an
active link.

I notice your claim that "fix-all" is very hard to dand. I presume you
mean "sand". I can't tell you what page that's on because they all have
the same URL. I don't like that sort of data hiding.

I like the story. Is there a point to substituting "avery" for "aviary"?

It took much too long to load with my dialup connection!

I liked the story.
